Release 1.11.0

The OpenVibe Frame. The shared navbar, footer and "shipped" views every OpenVibe site sits in were called the "chrome", which was borrowed jargon easily mistaken for the browser. They are now the Frame:

• openvibe-shared/frame is the server module (formerly openvibe-shared/chrome-ssr, which stays as a deprecated alias until 2.0.0).
• The navbar and footer read https://openvibe.network/api/frame (Network keeps /api/chrome as an alias for older copies) and send their page-view beacon to /api/frame/hit.
• They share window.OpenVibeFrame; OpenVibeChrome points at the same object.
• The browser cache key is ov_frame_v1.

No behaviour change.
